Foster has been handed another poor hand as he prepares his All Blacks squad for their two test tour to South Africa.
Ofa Tu’ungafasi has been ruled out of the tour due to a neck injury he sustained in the the third test against Ireland.
He will do his recovery at home hopefully to be available when the All Blacks return home next month for their test against the Pumas.
The prop will join Brodie Retallick, Jack Goodhue and fellow Blues prop Nepo Laulala who are all also still injured.
Uncapped Newell was called up to take his place in the squad for the tour to South Africa.
